IMPROVEMENT IN MEANS FOR VENTILATING AND DISCHARGING BlLGE-WATER FROM VESSELS.

Specification forming part of Letters Patent No. 164,191, dated June 8, 1875 application filed 4 April 10, 1875.

To all whom it may concern Be it known that I, DANIEL LEIBY, of Riverside, in the county ot' Northumberland and State of Pennsylvania, have invented certain new and useful Improvements in Wheel- Vessels; and I do hereby declare that the following is a full, clear, and exact description thereof, which will en able others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings and to the letters ot' reference marked thereon, which form a part of this specification.

The object of myinvention is principally to remove all foul air and b'ilge-water from vessels; and to this end the nature ot' my invention consists in providing a vessel with a suitable pump communicating, by a pipe and valve, with the bottom ot' the vessel, and by other pipes and valves with air-tight casings inclosing the paddle-wheels. It also consists in the construction and combination of parts as will be hereinafter more fully set forth.

In the annexed drawing, Figure 1 is a plan view of a vessel embodying my invention. Fig. 2 is a longitudinal vertical section of the same through the line x x, Fig. 1. Fig. 3 is a transverse vertical section through the line y 3/7 Figl' v A represents the hull of a vessel provided with two vertical openings, B B, in the longitudinal center of the vessel. In these openings are located the paddle-wheels U C, which may be arranged at any desired height, and they are covered on top by air-tight casings or wheel-houses D D. Between the wheels U O, at any suitable point in the vessel, is a pump-cylinder, E, with reciprocating piston G operated by any convenient means. From the bottom ot' this pump a pipe, b, leads to the interior of the vessel at the bottom, and on the bottom of the pump is an upward-opening valve, a, covering the end of said pipe. The pump-cylinder E is further, by pipes d d, connected with the openin gs B B above the Waterline, said pipes being' at their inner ends provided with outwardly-opening valves e e. The pump being in operation, it draws all the foul air and bilge-water from the interior of the vessel, and discharges the same into the wheelopenings .B B, and as the pure air from above at once takes the place ot' the removed foul air a continuous circulation ot` air may be kept up through the vessel, so as to perfectly ventilate the same. The casings or wheelhouses D being made air-tight, the air discharged into them by the pump Will be more or less compressed, so as to force the water in the openings B downward, and causing it to stand therein below the Water-line on the outside, thereby preventing the paddle-wheels from becoming too deeply immersed. This is also of great import-ance, as it is only the paddles that exert any force to propel the vessel.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a vessel constructed substantially as described, the combination of a pump, E G, the pipe b, with valve a communicating with the bottom of a vessel, and the pipes d d, with valves e c communicating with the wheelhouses thereof, as and for the purposes herein set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
